May 30, 2019 · Q: Shouldn’t TCP window scaling prevent packet loss? A: That is mostly correct – TCP will scale the flow of segments based on network conditions, but because the loss of TCP segments is the trigger for scaling back, it’s quite likely that the buffer had to be exhausted at least once already before TCP starts reducing window size. While libpcap will work with pretty much any NIC if you want to use PF_RING (which is strongly recommended due to performance benefits) you will need an Intel 82599-based NIC and ensure the Linux kernel is above 2. ipv4. c) and tcp_sndbuf_expand () (tcp_input. The bottom half / softirq removes the buffers from the ring for network stack processing, and reinitializes the ring with new buffers. The NIC then sends a hardware interrupt request, prompting the creation of a software interrupt operation to handle the interrupt request. the Linux man page tcp(7) mentions the TCP_NODELAY option to disable that (see also setsockopt(2)): TCP_NODELAY If set, disable the Nagle algorithm. Allow me to peek at the beginning of the Much simpler than TCP UDP packet integrity verification Queue incoming packets within Socket receive buffer; when the buffer is full, incoming packets are discarded quietly. This causes the socket buffer to overflow. Jan 20, 2014 · I have multiple threads that need to consume data from a TCP stream.
